A class of clock-cross-controlled sequences over GF(p) (p 2 is a prime number, 1 is a positive number) using the quadratic character of GF(p), i.e., LSRg[d0,d1,d2]-clock-cross-controlled sequences is introduced. When the feedforward function g(x1,x2,,xn), which is used as the controlling shift clock, is a quadratic form of GF(p), the properties of the period and the linear complexity of this sequences are discussed.
